Nothing to do with big data.

Big Data, or Big Data, refers to information that is so large in size that it cannot be captured, managed, processed, and organized in a reasonable amount of time through mainstream software tools for the purpose of helping companies make more positive business decisions.

The definition given by McKinsey Global Institute is: a data set that is so large that it greatly exceeds the ability of traditional database software tools to acquire, store, manage, and analyze it, and it has four major characteristics: massive data scale, rapid data flow, diverse data types, and low value density.
